Duplex stainless steel round bar

Duplex stainless steel round bar is downstream processed to seamless pipe, fitting, flange, shaft, pump valve, member bar and so on, the final products are widely used in LNG liquefied natural gas, chemicals, ocean industry, petrochemical engineering and some high-end industries.

022Cr22Ni5Mo3N duplex stainless steel is a kind of ferrite to austenite stainless steel, belong to the second generation of duplex stainless steel in the alloy. In the early 1980 s, our country began to develop and 022Cr22Ni5Mo3N  duplex stainless steel is 00 cr22ni5mo3n duplex stainless steel, the microstructure of ferrite and austenite F A each account for about 50%. It combines ferrite and austenite is the most useful performance: ferrite phase steel has high strength and resistance to chloride stress corrosion performance, austenitic phase steel has good toughness and corrosion resistance. S31803, therefore, has the very good resistance to chloride stress corrosion cracking, are better than ferritic stainless steel chloride pitting and crevice corrosion resistance, good common corrosion resistance, good resistance to sulfide stress corrosion capability. 022Cr22Ni5Mo3N duplex stainless steel, as a kind of good corrosion resistance, high strength, yield strength of austenitic steel for other 2-3 times), including the steel chromium and molybdenum content is very high, so has excellent corrosion resistance and uniform corrosion. Duplex microstructure ensures that the steel has the ability of high resistance to stress corrosion cracking, and high mechanical strength at the same time.
022Cr22Ni5Mo3N duplex stainless steel Product form Alloy round steel, seamless steel pipe, alloy pipe, alloy steel pipe), steel/alloy steel plate 022Cr22Ni5Mo3N duplex stainless steel application: Food industry, papermaking industry, power plant flue gas desulfurization equipment, offshore oil platform, desalting equipment special chemical environment equipment such as: oil pipeline and equipment, other chemical equipment. Used in oil refining, chemical fertilizer, paper making, petroleum, chemical industry and so on seawater high-temperature nitric acid and other heat exchanger and cold shower, and devices.
